摘要： Degradations in light emitting elements occur with the passage of time. The invention provides a method of driving a light-emitting device provided with a plurality of pixels, which includes a light-emitting means with a first and a second electrodes, a drive means for supplying the light-emitting means with a current in response to an analog video signal, and a setting means for setting a sustaining period and an off time period within a frame period. The method of driving a light-emitting device is characterized by including the steps of: supplying the light-emitting means with the current in response to the analog video signal during the sustaining period; and turning the drive means off thereby to make the light-emitting means nonluminous or making the first and the second electrodes identical in potential thereby to make the light-emitting means nonluminous during the off time period.

摘要： A display device which operates appropriately independently of the manufacture variations of each element formed over a substrate is provided without increasing the number of components. The display device includes an external correction circuit and a panel, and the external correction circuit and the panel are connected to each other through an FPC connecting portion. The panel includes a signal line driver circuit, a scan line driver circuit, a pixel portion, a monitoring element portion, a D/A converter and a constant current source. When mounting the D/A converter on a substrate, the number of external circuit components can be reduced without increasing FPC terminals by supplying a digital signal inputted to the D/A converter from a video signal line, and controlling the sampling timing of the digital signal with a signal used in the panel.

摘要： A problem in that a light emitting element slightly emits light is solved by an off current of a thin film transistor connected in series to the light emitting element, thereby a display device which can perform a clear display by increasing contrast, and a driving method thereof are provided. When the thin film transistor connected in series to the light emitting element is turned off, a charge held in the capacitance of the light emitting element itself is discharged. Even when an off current is generated at the thin film transistor connected in series to the light emitting element, this off current charges this capacitance until the capacitance of the light emitting element itself holds a predetermined voltage again. Accordingly, the off current of the thin film transistor does not contribute to light emission. In this manner, a slight light emission of the light emitting element can be reduced.

摘要： A semiconductor display device that operates normally at a room temperature may not operate normally at a low temperature. Meanwhile, in semiconductor display devices with the same circuit configuration and the same driving method, the higher the operating frequency is, the better the display quality is. Thus, a semiconductor display device the operating frequency of which is set on the basis of a room temperature may not operate normally at a low temperature. According to the invention, the temperature and the operating state of a semiconductor display device are measured to vary the operating frequency in accordance with the measurement result. More specifically, the operating frequency is decreased at a low temperature to obtain normal operation, while the operating frequency is increased at a room temperature and a high temperature to improve the display quality.
